A car of mass 1000.0 kg is traveling along a level road at 100.0 km/h when its brakes are applied. Calculate the stopping distance if the coefficient of kinetic friction of the tires is 0.500. Neglect air resistance.
A crate having mass 50.0 kg falls horizontally off the back of the flatbed truck, which is traveling at 100 km/h. Find the value of the coefficient of kinetic friction between the road and crate if the crate slides 50.0 m on the road in coming to rest. The initial speed of the crate is the same as the truck, 100 km/h.
A recycling bin has mass 3.0 kg and is pushed upward along an incline angled at above the horizontal. The bin moves with constant speed under the action of a 26 N force acting upward along the incline. The surface of the incline produces a frictional force that resists the motion of the bin. What magnitude force must act up and parallel to the incline for the bin to move downward along the incline at constant speed?
